The sofa bed adopts USB design, and there are 2 USB interfaces on the side of the sofa. When the phone is dead so you can charge your electronics without leaving the sofa bed, you don't have to worry about lying on the couch playing games, but the charging cable isn't long enough. The storage bag on the side is perfect for storing mobile phones, earplugs, remote controls, etc. You can watch your movie from the comfort of your couch.
